ABSTRACT:
A piston machine has a piston movable in a cylinder. The piston has a peripheral surface defining a clearance space with the inside cylinder surface. An annular slot in one of the surfaces is surrounded by, and communicates with, an annular chamber forming part of the one surface and an annular hollow conductor in the chamber has an apertured wall portion facing the slot. An anode and at least one cathode contained in the conductor are operable to cause electrons to be emitted from the cathode and to become trapped by gas molecules contained in the conductor so that the gas molecules are converted into gas ions, to cause the gas ions to move through the apertured wall portion and the slot into the clearance space, and to cause electric fields to confine the gas ions in the clearance space to form a gas ion barrier which seals the clearance space.
